SBUS<sb>:UART:POLarity <Polarity>
Defines the logic levels of the bus. The idle state corresponds to a logic 1. The start bit
corresponds to a logic 0. "Idle high" (high=1) is used, for example, for control signals,
while "Idle low" (low=1) is defined for data lines (RS-232).
Suffix:
<sb>
.
1...4, index of the serial bus
Parameters:
<Polarity> IDLLow | IDLHigh
*RST: IDLHigh
Usage: Asynchronous command
Manual operation: See "Polarity" on page 309
SBUS<sb>:UART:RX:HYSTeresis <Rx hysteresis>
Sets the hysteresis for the Tx line.
Suffix:
<sb>
.
1...4, index of the serial bus
Parameters:
<Rx hysteresis>
Usage: Asynchronous command
Manual operation: See "Threshold" on page 310
SBUS<sb>:UART:RX:SOURce RXSource
